Containers vs virtual machines: differences, pros and cons
Containers vs virtual machines compared: how Docker and LXC share the host kernel while KVM VMs run their own, plus isolation, performance, density and when to combine both.
Create a KVM virtual machine in Proxmox VE step by step
Create a Proxmox VM from an ISO: upload the image, pick CPU type, memory, VirtIO disk and network, install the OS through the console and add the QEMU guest agent.
Create a KVM virtual machine with virt-install
Use virt-install to create a KVM virtual machine from the command line: choose CPU, RAM and disk, attach an ISO or cloud image, connect a bridge and finish the install over VNC or serial console.
Create a Linux server lab VM in VirtualBox
Install VirtualBox on Windows, macOS or Linux, create an Ubuntu Server VM, choose NAT or bridged networking, set up port forwarding for SSH, and use snapshots to practise safely.
Desktop hypervisors compared: VirtualBox vs VMware Workstation vs Hyper-V
Compare desktop virtualization tools for Windows, macOS and Linux: VirtualBox, VMware Workstation and Fusion, Hyper-V, Parallels and UTM, on cost, performance, features and compatibility.
Enable Hyper-V on Windows Server and create a virtual machine
Install the Hyper-V role on Windows Server with Server Manager or PowerShell, create an external virtual switch, build a Generation 2 VM and connect to it, with common fixes.
How to choose a virtualization type: VM, container or bare metal
A decision guide for picking between virtual machines, containers, microVMs and bare metal based on isolation, OS needs, performance, density, budget and operational skills.
Install and enable the QEMU guest agent in Proxmox VMs
Enable the QEMU guest agent so Proxmox can see VM IPs, shut down cleanly, freeze filesystems for consistent backups and run commands, on Linux and Windows guests.
KubeVirt explained: run virtual machines on Kubernetes
How KubeVirt lets Kubernetes manage KVM virtual machines alongside containers, its main resources (VirtualMachine, DataVolume), requirements, a basic example and when it makes sense.
Pass a USB device through to a Proxmox VM
Give a Proxmox VM direct access to a USB device such as a licence dongle, Zigbee stick or UPS: pass by vendor/product ID or by port, and know the migration limits.
Proxmox templates and clones: linked clone vs full clone
Turn a prepared VM into a Proxmox template, choose between linked and full clones, clean machine IDs before cloning, and deploy new VMs in seconds.
Resize a Proxmox VM disk and grow the filesystem
Increase a Proxmox VM disk in the web UI or with qm resize, then grow the partition, LVM and filesystem inside Linux or Windows so the extra space is usable.
Set up the Proxmox VE firewall for the host and VMs
Enable the built-in Proxmox firewall safely: allow the web UI and SSH first, then add datacenter, node and per-VM rules, security groups and IP sets.
Take and roll back Proxmox snapshots for VMs and containers
Use Proxmox snapshots before risky changes: which storage supports them, how to include RAM, roll back or delete them, and why a snapshot is not a backup.
What is virtualization? How servers run many virtual machines
A plain-English explanation of virtualization: hypervisors, virtual machines, containers, and why almost every VPS and cloud server today runs on virtualised hardware.
